Retirement Benefits [Abstract] |
Retirement Benefits | Retirement Benefits The Company has a defined contribution plan, under Section 401(k) of the Internal Revenue Code, which provides retirement benefits to most U.S. employees. For all employees who choose to participate, the Company matches employee contributions at a 100 percent rate, up to 3 percent of the employee’s compensation. For employees not covered by a defined benefit plan, the Company contributed an amount equal to 2 percent of the employee’s compensation. Employer contributions totaled $11.0 million in 2022, $10.0 million in 2021 and $8.7 million in 2020. The Company’s postretirement medical plan provides certain medical benefits for retired U.S. employees. Employees hired before January 1, 2005, are eligible for these benefits upon retirement and fulfillment of other eligibility requirements as specified by the plan. The Company has both funded and unfunded noncontributory defined benefit pension plans that together cover most U.S. employees hired before January 1, 2006, certain directors and some of the employees of the Company’s non-U.S. subsidiaries. The Company restructured one of its U.S. qualified defined benefit plans in 2021. Under the restructuring, the plan transferred $63 million of liabilities and assets associated with certain plan participants to an insurance company via the purchase of a group annuity contract, and the Company recognized a $12 million settlement loss, included in 2021 other expense, net. This charge represents the acceleration of deferred charges previously accrued in accumulated other comprehensive income. Subsequent to the transfer of pension obligations, the smaller of the two pension plans was merged into the larger plan in December of 2021, with the larger plan being the surviving funded pension plan. The benefits offered to the plans’ participants were unchanged. For U.S. plans, benefits are based on years of service and the highest 5 consecutive years’ earnings in the 10 years preceding retirement. Plans are funded annually in amounts consistent with minimum funding levels and maximum tax deduction limits, although the Company may make additional voluntary contributions from time to time to improve the funded status of its plans. Investment policies and strategies of the U.S. funded pension plan are based on participant demographics. As the plan covers active participants and retirees with higher benefit amounts, investments are based on a long-term view of economic growth and weighted toward equity securities. The primary goal of the plan’s investments is to ensure that the plan’s liabilities are met over time. In developing strategic asset allocation guidelines, an emphasis is placed on the long-term characteristics of individual asset classes, and the benefits of diversification among multiple asset classes. The plan invests primarily in domestic and international equities, fixed income securities, which include treasuries, highly-rated corporate bonds and high-yield bonds and real estate. Strategic target allocations for plan assets are 53 percent equity securities, 42 percent fixed income securities and 5 percent real estate and alternative investments. Plan assets are held in a trust for the benefit of plan participants and are invested in various commingled funds, most of which are sponsored by the trustee. The fair values for commingled equity, fixed-income and real estate investments are measured using net asset values, which take into consideration the value of underlying fund investments, as well as the other accrued assets and liabilities of a fund, in order to determine a per share market value. Certain trustee-sponsored funds allow redemptions monthly or quarterly, with 10 days or 60 days advance notice, while most of the funds allow redemptions daily. The plan had unfunded commitments to make additional investments in certain funds totaling $2.3 million as of December 30, 2022 and $2.4 million as of December 31, 2021. The Company maintains a defined contribution plan covering employees of a Swiss subsidiary, funded by Company and employee contributions. Responsibility for pension coverage under Swiss law has been transferred to a Swiss insurance company. Plan assets are invested in an insurance contract that guarantees a federally mandated annual rate of return. The value of the plan assets is effectively the value of the insurance contract. The performance of the underlying assets held by the insurance company has no direct impact on the surrender value of the insurance contract. The insurance backed assets have no active market and are classified as level 3 in the fair value hierarchy. Assets of all plans by category and fair value measurement level were as follows (in thousands):

Changes in discount rates used to value pension obligations were the main drivers of actuarial gains in 2022 and 2021.

The accumulated benefit obligation as of year-end for all defined benefit pension plans was $297 million for 2022 and $388 million for 2021.

Several sources of information are considered in determining the expected rate of return assumption, including the allocation of plan assets, the input of actuaries and professional investment advisers, and historical long-term returns. In setting the return assumption, the Company recognizes that historical returns are not always indicative of future returns and also considers the long-term nature of its pension obligations. The Company’s U.S. retirement medical plan limits the annual cost increase that will be paid by the Company to 3 percent. In measuring the accumulated postretirement benefit obligation (APBO), the annual trend rate for health care costs was assumed to be 8.5 percent for 2023, decreasing each year to a constant rate of 4.5 percent for 2038 and thereafter, subject to the plan’s annual increase limitation. The Company expects to contribute $1.9 million to its unfunded pension plans and $1.8 million to the postretirement medical plan in 2023. The Company will not be required to make contributions to the funded pension plan under minimum funding requirements for 2023. Estimated future benefit payments are as follows (in thousands):
| Pension Benefits |  | Postretirement Medical Benefits
2023 | $ | 15,583 |  |  | $ | 1,763 |
2024 | 17,035 |  |  | 1,748 |
